METAL POLE CONSTRUCTION.

Application filed April 18, 1922. Serial No. 554,875.

To (ZZZ whom 2'25 may concern:

Be it known that we, ARTHUR W. WRIGHT and BENJAMIN'F. IBAGH, citizens of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented new and useful Improvements in Metal Pole Construction, of

. which the following is aspecification.

This invention relates to metal posts intended for use as telegraph and telephone poles, electric-conductorpoles, and for other purposes requiring support poles or posts of relatively inexpensive but durable construction.

An object of the invention is to provide a post having a simple structure which may be readily and inexpensively made, and whichwill give accurate resistance against both transverse and longitudinal strains.

In the accompanying drawings there is shown one form of a post in which the invention may be embodied, and in the draw iig. 1 is a side elevational view of the top portion of the post,

Fig. 1 is a side elevational View of the bottom portion of the post,

Fig. 2 is a cross sectional view on the line 2-2 of Fig. 1, i

Fig. 3 is a cross section showing the modilied form of horizontal brace construction, and

Figs. 4:, 5 and 6 are cross sectional views showin further modifications of the horizontal brace construction. 1

Referring to the drawings for a more detailed description, the post is preferably of metallic construction and comprises a plurality of longitudinal or vertical rods 10 of any suitable metallic material having satisfactory durability. Strong wire or tubing or solid rod maybe employed. The rods have a plurality of reverse bends 11 to form uprights of zig-zag shape. Any number of rods may be employed in the construction of the post, but in the illustrated structure, which typifies the invention, eight rods are employed, and they are arranged with the bends in the several rods equidistantly spaced with respect to each other, and positioned in alignment in spaced horizontal planes along the rods.

a By positioning the bends inalignment the portions of the rods between the succeeding bends alternately converge in an upward direction, as, for example, at 12, and diverge, as at 18 (Fig. 1). It should be observed that the rods at all times maintain the same lateral position with respect to each other, that is to'say, they do not cross between the bends. By this arrangement of the longitudinals or uprights the rods between the bends are relatively arranged so that a very satisfactory structure for maintaining the rigidity of the post against vertical and transverse strains is provided.

The structure is horizontally braced by means of spaced'horizontal stays or braces 14 (Figs. 1 and 2) which are spaced apart along the rods and are positioned, preferably, at the bends in the rods. The horizontal stays should preferably be in the form of endless members, such as the annular members shown clearly in Fig. 2, so that the rods at their bends may be secured thereto. The braces 14 are provided with peripheral radially extending lugs 15 positioned between the adjacent members of rods at their bends. Suitable clips 16 having inwardly bent end portions 17 are secured to the lugs by means of rivets or bolts 18 and clamp the rods to the braces or stays.

As will be noted from an inspection of Figs. 1 and 2, one of the braces, in the present instance the top brace, should be provided with means, such as the lugs or cars 19, for supporting a cross arm 19 such as is used upon a conductor or telephone pole. Bolts 20 serve to clamp the cross-arm suitably to the brace. As will be observed from an inspection of Figs. land 1, the post varies in cross-sectional dimension, it being of considerably greaterdiameter adjacent its base than at its top. The top may be provided with-a suitable cap plate 20, and its base portion, which extends into the ground, maybe enclosed in cement or concrete 21, which serves to afford additional rigidity for the structure.

The construction of the horizontal braces and the means for securing the rods to the braces may be materially varied from the structure shown in Figs. 1 and 2 Withoutv departing from the scope of the invention. For instance, it is possible to weld the verticals to the horizontal braces, and with this arrangement it is desirable to form the braces in the manner shown in Fig. 3, in which the brace 22 is shown as formed with a plurality of radially opening recesses 23, each recessforming a seat for a pair of superposed rods 10 which may be welded together in the seat. y

In Fig. 4 a horizontal brace is shown which is formed of a plurality of arcua-te sections 24, 25. Sections 24 are formed with inwardly extending end portions 24', and the sections 25 with outwardly extending end portions 25. The adjacent end portions' are spaced apart circumferentially of the brace. a sufficient distance to form a space adapted to receive the longitudinals 10, and rivets or other suitable securing means 26 passing between the pairs of longitudinals at circumferentially spaced points about the brace secure the longitudinals in position and the various sections of the i brace together.

The form of. brace shown in Fig. 5 comprises an annular member 27 having a plurality of radially opening recesses 28 forming-seats for theuprights l0, rivets or bolts 29 provided. with plates or washers 30 po-- sitioned over the uprights maintaining the latter in position. Additionally, the recesses are provided with shoulders 31 which extend over the uprights.

The brace structure shown in Fig. 6 differs from that shown in Fig. 5 only in the general'shape' of the recess, the structure coniprising a plurality of recesses or seats 32 which are intended for the reception of round uprights 10. The uprights are maintained'in. theirseats by means of wedges 33 which are positioned between the members of the'pairs 0t "uprights and held in position by means of bolts or rivets 34.

It should beunders'tood that'such modifi cations be made in the illustrated and described structure as come within the scope of the invention, which is more definitely defined in the following claims.
